TPS53667: realizing a 420A design

Part Number: TPS53667

Hi , I see on the info page that the controller will do up to a 420A design. I have the EVM kit and it specify 180A . I do notice the power stages are either not out yet or special as there is no info on them. I was going to ask what is the absolute maximum the EVM will do, I know I can set limits out the roof but other than running it until it fails I don't know.

Thanks,

    Hi Michael,

    A 420A design would be pushing the CSD95490 FETs to their limits and would be a challenging design on its own. Unfortunately the eval board cannot handle such high load currents as it was only designed to 180A-200A. With that much current the regulator would shutdown rather quickly from an over temperature fault. I don't recommend pushing the eval board that hard.

    Thanks,

    Carmen

    I kind of thought this might be the case but was not sure, like I said I saw on the info page that is was listed at 420A but did not know if that was even possible. Something else I read made me think, so the output stages need to be all together ? I was looking at a design that might have them placed around a groups of ASICs and not at one one of the board feeding power across. I don't know if I need 420A just looking at what can be done two converter setups wouldn't be out of reach but I am guessing the CSD95490 FETs not being available yet or for some time.
    Thanks

    Hey Michael,

    Chris from the FET team has offered to answer your questions about the CSD95490 availability and acquiring samples. He can also have his team answer your technical questions too regarding layout. Please send him an email at cbull@ti.com.

    Cheers,

    Carmen
